SPECIFICATION forming part of Letters Patent No. 542,310, dated July 9,1895.

Application filed March 2, 1894. Serial No. 502,153- (No model.)

To L7/Z whom t may concern:

Be it known that LJONAS PRINTZ, of Omaha, in thecounty of Douglas andState of Nebraska, have invented certain usefullmprove-` ments inRailway-Car Wheels and Tracks; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specification.

This invention has relation to a new and novel improvement inrailway-car wheels and tracks, the object being to provide a simplemeans whereby the cars can be more readily propelled up an incline. A

In a great many cities where car-line grades are of necessity very steepmuch time is lost 'and power expended in carrying cars up the incline.During moist or icy weather a great many cars almost become stalled bythe wheels revolving upon the track without moving forward. Thisslipping of the wheels is of course prevented in a degree by scatteringsand on the rails; but as the riding-surface of the rail is narrow thesand soon works off. To provide a means whereby the cars can be morereadily propelled up an incline is the object of my device.

In the accompanying drawings, Figure 1 shows a view, with the railspartly in section, of car wheels and trucks embodying my invention. Fig.2 shows an enlarged detail of one of the trucks, while Fig. 3 shows aside view thereof.

A represents an axle of the usual size and conformation with the twowheels B B, which are as usual fixedto the axle A. These wheels areprovided with the usual driving and guiding fianges. The guiding-{iangeC in this -instance, however, extends at an angle to the wheel A proper,and comprises the guide- Iiange 2l and the friction-flange proper 3.This flange 3 of course forms an integral part of the wheel proper. Tofurther insure the efficiency of this flange 3, I provide the same witha number of corrngations or depressions 5, distributed about this flange3. The track upon which'this wheel is adapted to run comprises the mainportion D, having the usual riding-surface and being'provided belowlwith the approximately circular seating 7.

side with the angular seating 12, adapted to accommodate the'angularportion of the friction-rail E. This friction-rail is also corrugated orscalloped, having the depressions 15, within which those of the wheelreadily work. Now these two-part rails E D are su pposed to be placedwithin the system at all points where gradesI are encountered. As soonas a car equipped with my truck strikes this track, the trucks leave theriding-surface of this rail D and are guided upon the friction-rails E,as shown in Fig. l, so that these anges support the whole weight of thecar. By means of the bolts F these flanges may be given adjustment. Asthe upper edge of the friction-rail E wears off and out, theflangesection C is simply'reversed, so as to present the lower surfaceof this iiange, so as to make the same reversible and interchangeable.It is of course understood that this ange C could be without thecorrugat-ions or scallops, as shown in Fig. 1, where the friction-dangeof one of the wheels has been left perfectly smooth, as has also thefriction-rail. It is also understood that, ifdesired, the rail D couldbe cast with an upwardly-extending frictionrail E.

Now, having thus described my said invention, what I claim as new, anddesire to secure by United States Letters Patent, is-

1. The combination with a car axle having suitable wheels, said wheelsbeing provided with outwardly extending friction flanges, said frictionflanges being scalloped, of atwo part rail comprising a main supportingsection in combination with afriction rail, transversely in the shape ofan isosceles triangle, the base of said friction rail being positionedvertically, and being reversibly and adjustably secured to the main partof said rai the angular sides of said friction rail being IOO i adaptedto engage the friction flanges of said section in the form of anisosceles triangle, wheels, to support the same, all substantially andprovided with the transvere opening, 9, as and for the purpose setforth. and the connecting bolts, F, all arranged to 2. The combinationWith the car axle, A, operate substantially as and for the purpose r4 5provided with the Wheels, G, having the fricset forth.
